'lO ALL WHOM I'l MAY GDNCERN:

Be it known that I, DANIEL S. LOY, of Grucehain, in the county of Frederick, and Stute of' Maryland, have invented u. new and useful Improvement in 'luyeres andI do hereby declare the following to he a full, clear, and exact description of the saine, suicient to enable one skilled in the art to which the invention'appertains to make use of it, reference being had to the accompanying drawings, which form a part of this speciication, and in whieh- Figure l is a vertical section` Figure' 2da a vertical section on line y y, g. 1.

Figure 3 is a top view, lid removed.

Figure l is a top view, lid in place.

Figure 5 is a view of a niodied form of blast-plate.

Figure 6 is a. section on line z e, hg. 5.

The air from the bellows entering the blast-chamber acts upon a Wing, and actuates the water which closes the lower aperture of the chamber. When the blast ceases the valve opens, discharges the cindors, and admits the passage of air to the tire. Different forms of blast-plates are used as cups fitting upon tho riin which bounds the upper end of the blast-chamber, and the cinders are conducted by an adjustable pipe in such direction as may be suitable for their discharge. K

In the drawings, A is the blastchainber, and B the nozzle of the bellows through which air is blown into the chamber. At the lower end of the chamber is an opening, C, for the discharge of cinders, and the pipe D is a continuation oi` the discharge, and its opening can be presented in any direction where it is convenient for the ashes to bc placed. The opening C is closed by a valve, E, which is suspended from the arm F of the shaft G, which hasits bearings in removable cheek pieces which slide into vertical grooves in the side of the bha-naher A. When a blast enters the chamber it impinges 'against the wing H, and rotates the shaft, dropping the valve on to its seat. When the blast ceases, the counterpoise Weight, Z, lifts the valve. At the upper edge of the chamber A is-a bead, a, upon or within which fits a Harige of the blast-plate J; this plate has a slit or opening in it through which air issues to supply the ire. Different. plates, having openings of different sizes and forms, are provided for different kinds of work. To prevent the cinders -from interfering with the moving parts, a cruciform plate, K, is provided, which rests upon a shelf` in the chamber, and sheds theoinders off the shaft G and its adjuncts.

Having described my improvement, what I. Olaiin as new therein, and desire to secure by Letters Patent, is-

1. The valve E, in combinatio with the weighted lever F and wing H, substantially as and for the purpose described.

2. I claim the vibrating wing H, arranged and supported in the manner described, in combination with the valve E and blast pipe B, as andfor the purpose explainedA l 3. In a tuyere, constructed as herein described, I claim the cap plate or shield K, formed and applied in the manner and for the purpose specified.

'lo the above specification of my improvement in tuyeres, I have signed my hand this eleventh day of October, 1866.

DANIEL S. LOY.
